Description
Technical field
The invention belongs to medical instruments fields, and in particular to a kind of multifunctional tumor removing scissors.
Background technique
Tumour may occur for any position of human body, mostly benign, and benign tumour has a complete tumor wall and normal tissue viscous
Even.For surgery system benign tumour some need to be rejected.Currently, peeling operation benign tumour with scissors, knife handle or
Cyst wall is separated and is kept tumour integrality with surrounding tissue row passivity or sharp property by index finger, to take out.Existing tumour removing
Scissors when in use, is easy to make tumour to rupture discharge to abdominal cavity and pelvic cavity, and makes tumor recurrence, and expansive force declines after cyst wall rupture
Increase the difficulty of removing.When removing tumour using finger, although not easy damaged tumor wall, finger is shorter, is not readily separated tumour
Lower section and basal part.
Currently, the cutting tool that existing tumor dissector uses is integrally formed cutter hub, length is non-adjustable, answers
Used time needs once cut completion, cutting efficiency is lower at the adhesion of the cutting tumour and normal tissue of a part a part.
A kind of tumor dissector is disclosed in the patent that Authorization Notice No. is CN 205391141U comprising drag hook is solid
Fixed pipe, and drag hook fixing pipe is socketed with pipe sleeve, the both ends of pipe sleeve are stretched out at drag hook fixing pipe both ends, and drag hook fixing pipe one end is equipped with
Several fixing pieces are hinged with the drag hook with drag hook extension rod on fixing piece.It need to only be mentioned when needing to take out tumor mass
Drag hook fixing pipe is drawn to push casing, two drag hooks are gathered to center, clamp tumor mass, can take out tumor mass.But
Due to drag hook band stock, length is non-adjustable, and stock is not adapted to tumor surface, and cutting effect is poor, and application value is lower；Drag hook is only
It is articulated on fixing piece, without retaining mechanism, hold mode cannot be stablized, when application is inconvenient；It does not suck blood dirty mechanism,
Blood stains may cover cutting part and influence treat doctor cutting operation, be unfavorable for the diagnosis and treatment of patient；And due to stock front end
Hook is bent to, width is larger, biggish space is needed when protruding into tumor periphery, to the normal tissue of tumour circumferential perimeter
Injury it is larger.
Summary of the invention
The purpose of the present invention is: it is intended to provide a kind of multifunctional tumor removing scissors, can be set according to healthcare givers
Frequency, be automatically performed shear action, applicability is preferable, also helps the wound reduced to the normal tissue of tumour circumferential perimeter
Evil, application value is higher, and can disposably cut down entire tumour, and cutting efficiency is high；Also there is the mechanism for drawing blood stains,
Convenient for the cutting operation of doctor.
To realize the above-mentioned technical purpose, The technical solution adopted by the invention is as follows:
